Efficiency of arc production of fullerenes versus discharge chamber geometry. II: Double-sided gas delivery and 3D geometry

Based on the model suggested in part I of this work and analysis of a chamber for arc production of fullerenes, two ways of gas delivery to the chamber, one-sided pumping of the gas (from the side of the anode) and double-sided pumping (from both the cathodic and anodic flanges), are considered. In the latter case, the efficiency of fullerene extraction from the discharge chamber rises substantially. The axisymmetric 2D case considered earlier is extended for the 3D geometry of the chamber, where gas outlet is accomplished through the side wall of the chamber. (c) 2005 Pleiades Publishing, Inc.
